. do hereby declare the following to be a full,

clear, andexact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates toimprovements in nut locks and more particularly to that class employing a disk or washer provided wit-h spring dogsto engage shoulders in the base of a nut,--the object of the invention being to so construct a nut lock of the type specified that a maximum number of adjustments of thenut with a minimum number of dogs on the disk and shoulders on the nut, can be effected, and so that some of the dogs on the disk will rest idly, while the remaining dogs will be in active engagement with shoulders von the nut to lock the latter.

1. s Fig. 3 is a sectional view on the line y-y of Fig. 2. Fig. 4 2s a 'rear face new .ofthe nut, and Fig. 5 is a face view of the washer at.

1 represents a threaded bolt provided with v longitudinal grooves 2 and 3 represents a nut on the bolt. A disk or washer 4 is dispo ed between the inner face of the nut and t object 5 through which the bolt passes, said disk or washer being provided with in wardly projecting lugs 6 to enter the longitudinal grooves in the bolt to prevent said disk from turning. The nut 3 is provided in its inner face with an annular series of deep notches 7, at one end of each of which a shoulder 8 is formed to be engaged by dogs 9 projecting from the disk or washer 4:. The dogs 9 are made integral with the disk or Washer 4,-being stamped therefrom and bent laterally thus forming spring dogs. The sprin dogs 9 are so arranged or spaced apart with relation to the spacing apart of the shoulders 8 formed by the notches 7 in the nut, that some of said spring dogs .will engage said shoulders while the others will rest idly in the adjacent notches 7 in the nut without engage ment with the shoulders 8 which form the end walls of such notches.

In the drawings I have shown the washer as being provided with four spring dogs Having fully described my invention'what I I claim as new and desire to tars-Patent, IS,

The combination with a threaded bolt and secure by Leta nut provided on its inner face with a se ries of annularly arranged notcheswhich are gradually inclined from the surface of the nut to their dog engaging shoulders, of a metal washer provided with a series of annularly arranged spring dogs adapted to enter the notches in the nut, the spring dogs of the washer being so spaced apart with relation to the dog engaging shoulder of the nut, that only part of the dogs will engage some of the shoulders on the nut, while the remaining spring dogs will in part rest idly in the notches 6f the nut and out of engage-merit with the dog engaging shoulders, and means for preventing the washer from turning on the bolt, substantially as set forth.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
